CHANGEABLE-PICIURE ADVERTISING APPARATUS.

Application filed June 16, 1525, Serial No. 37,568; and. in Germany May 7, 1925.

Advertising apparatus is already known in which a series of changing pictures is produced and in which the separate or individual pictures are divided into strips and 5 so secured on frames that they press through one another and by changing'opposit-e' displacement of the picture frames one or the other alternately appears, whilst the others remain covered.

All these apparatus have, however,-the disadvantage that they work very inefiiciently and that they only permit of the production of a very limited number of pictures heretofore at most three. This inconvenience originates from the fact that the dri-v ing arrangements in apparatus of this class heretofore extant were completely unsuitable. The production of the pictures in the aforesaid apparatus effected by a lifting or raising disc which is provided on its periphery with projecting lugs and effects a periodic rotational movement at intervals. It follows that the production of the pictures takes place at intervals and therefore atthe change two pictures always appear. partially overlapping one another and the lifting or raising. disc working Without energy is often unable to execute the displacement against the friction of the frame. The arrangement of the projecting lugs on the pe.

riphery of the lifting or raising disc limits, however, the number-of the movable picture frames to two at the most as further levers cannot be used without mutually hindering each other.

A further disadvantage of the hitherto second picture there simultaneously appears a third picture. All these disadvantages are avoided by the advertising apparatus according to the present invention which possesses such a form that any suitable number of changeable pictures can be provided for exhibition.

The present invention effects the movement of the frames by a uniformly rotating disc which is provided with striking pins of different lengths extending in an axialdirection and increasing in length in the opposite direction to that of the direction of rotation. In the path of these striking pins is arranged a seriesof levers lying behindone another and projecting at different distances from the disc, which levers are rocked in succession by the relevant striking pins able number of picture frames movable, the

arrangement thus resulting in that theentire number of pictures canbe fully changed by the insertion or removal of the frames and the increase or decrease of the striking pins arranged in the direction of rotation of the driving disc, the said pinsbeing of increasing lengths.

-& furtherimprovement of the driving arrangement consists in that the same is provided with a catch arrangement which'retains the frames in the direction in which they shall be individually moved and which are only released at the beginning of the systematic movement of the respective'pioture frame. The catch arrangement consists convenientlyo'f a'pa'w'l of hell crank formationlinked to the slide rail one arm of'the said pawl being supported against a fixed stop whilst the other arm of the pawl projects into the path of the respective slide rail actuating lever so that the lever moved forward by the driving disc at first lifts the pawl over the striking pin and then effects only the displacement of the slide rail with the frame. g p

A. further improvement of the invention consistsin that the apparatus has a lighting arrangement provided at the front of the apparatus. In picture advertising apparatus known hitherto the lighting arrangement was arranged behind the pictures and this was disadvantageous from the point of View that the pictures in consequence of the picture strips covering one another appeared likewise striped. They were only faintly illuminated and this had the effect of alter- 'ing or disturbing the impression of the re spective pictures more particularly by reason of the light rays falling through the spaces between the picture str ps.

According to the present invention the lighting is effected by tubular lamps which are secured on the inside of the front window frame of the'casing containing the mechanism, the

said tubular lamps being covered above and Ill) below.- The tubular lamps can be readily removed and replaced without disturbing the wiring connections. In this manner an efficient and uniform lighting of the picture surface is obtained all shadows on the picture strips being avoided. V

In order that the invention may be clearly understood and readily carried into practice, reference is made to the accompanying drawing which shows a constructional form in accordance with the present invention for producing five pictures.

Figure 1 shows a back view of an advertising apparatus in accordance with the present invention.

Figure 2 is a front view of the same showing'the window frame partly broken away.

Figure 3 is a vertical cross section of the apparatus.

Figure 4 shows a side view of the driving arrangement.

Figure 5 is a driving arrangement looking on the driving disc.

Figure 6 is a plan of Figure 5. Figures 7 to 11 show successive positions of the picture frame, Y

The'pictures to be produced are in a manner known per se divided into small pictures strips a'and secured on frames 6 one of which is fixed,the others being displaceable. The fixedframe is indicated at 6 and the movable frames at 6, b b b the associated part-shearing the same references. a indicates the picture strips of the stationary frame and a, a a a indicatev the picture strips of the movable frames respectively. The movable frames 6 to 6 whose picture strips a to at press through one another and mutually overlap are guided and supported by means of straps or slide members 0', 0 c o on a cross bar cl of the fixed frame a and extending across their planes and lyin in thesame plane as the cross bar (Z so that the whole frame can be inserted as a composite piece into a casing e. The casing is pro-' vided on its front side with a window through which the plctures are seen and carries the lighting arrangement and the driving mechanism for the movable frame.

The driving arrangement especially consists in a driving disc 7 to which a constant uniform rotational movement may be imparted by means of a worm g and gearing h, the latter being driven by a cord or belt pulley 2' which may receive its motion from an electric motor M. Striking pins 70, 70 I0 7: are provided onthe driving disc and are removably fixed thereto, which pins are disposed parallel to the axis Z and extend over the plane of-rotation of the driving disc, the said pins being of different lengths so that the pin 70' actuating the first frame 1) is the shortest, the other pins being of successive increasing lengths. These striking pins'may be arranged concentrically round a circle or the said triking pins of any desired number may be arranged concentricallybut on circles of different diameters on the driving disc Lugs m, m m m provided on leversn. n if, n respectively are arranged in the path of the ends of the striking pins 70 to 70 Which levers are rotatably supported on a common shaft 0 su. )orted h the frame fne levers a of the driving arrangement. 7 to a engage with slidable rails g, g g j" which; are provided with recesses 1" ror the heads a of the levers n to at. One t of a bell crank lever u projects into the re- 7 cess in each slide rail, there being a bell crank lever. for each slide rail. The upper end 4) of the bell crank levers 1n the position of rest engage behind a fixed lug or stop w k and. being. supported "h ereagainst. On the end of each slide rail Q1: to is a forked member a, 50 5, m m respectivelylwhich ene s re iewer 1 51/ 3/ e p ct y which s rigidly connected with the respective one of the movable frames 6 to 5 The movement of the picture frame takes 5 place in'such manner that the frames Z) to 5? lying behind the fixed frame 5 (see Figure 7) are displaced serially in the same direction so that theirpicture strips apush themselves in front of the picture strips of the preceding frame, The individual .frames are displaced bythe frame a of the associated striking pinflc on the driving disc 7 against the lug m of the lever extending under the shaft 0. The result is a rocking of the lever a the head 8 of which engages in the recess a of t ieslide rail and at first bears against the lower lever if of the pawl n in order to rock its axis so that the lever q is raised over the pin or stop a and the slide .ra-il Q" is freed. At this moment the head 8" strikes against the wall of the recess 1"- and displaces the slide rail 9 as shown in dotted lines in Figure 5. The

fork 00 is thus actuated and in its movement it takes the pin 3 with it and therefore the lit? frame 5 and thus causes the appearance of the picture secured to the frame 6, Figure 8, wherein the picture of the fixed frame was hitherto visible, Figure 7. The movement of other picture frames takes place in a similar manner so that these appear in succession according to the manner shown in Figures 7 to 11.

I Should all the movable frames 6 to b be displaced and their pictures exhibited, Figure 9,- the movable f ames Z) to b inclusive are simultaneously restored again to their position behind the fixed or stationary frame 6. This is effected by a further pin 2 whichis positioned on a larger diameter than the other striking pins 70 to k and strikes against a lateral projection j or lug on the lever n lying in its path, the said' 6 or its slide-member 0 respectively, will cause all the other slide-members c to. c and their frames bg to b to move in the same direction by pushing them out of its path to their original position. ,In this manner all movable frames 6 to b are brought to their original positions at the same time.

The casing e is provided onthe front side with a window a or opening (Figure 2) which may be glazed or closed by a sheet of clear transparent material and the pictures appear in the frame 1 thereof,

Figure 2. Behind the upper andthe lower window frame guides is arranged a tubular electric lamp 2, which receives its current through resilient slide-contacts 6. By this arrangement it is possible to enclose the lighting arrangement together with the window 2 in the casing without disturbing or disconnecting the wiring connections or unscrewing or removing the lamps. The opening in the casing is thus quite free and the picture frames can readily be removed as a composite or single'unit.
